SPECIFICATION forming part of Letters Patent'No. 465,013, dated December 15, 1891.

Application filed May 2,1891. Serial No. 391,355. (No model.)

To all whom, it may concern.-

Be it known that I, FRANQOIS FERNAND BOURDIL, ot' the city of Paris, France, have invented a Liquid Atomizer or Pulverizer, of which the following is a full, clear, and exact description. I

This invention relates to apparatus for atomizing or pulverizing liquids; and it con sists, essentially, in the combination of a flexible diaphragm having'a central aperture,

' with a post or spindle passing through it having a shoulder, against which the liquid, divided into a thin stream by being forced between the post and diaphragm, is projected, and thereby becomes pulverized. This post is fixed into a box, of which the diaphragm forms the cover, to which the liquid is sup-' plied under pressure. 7

Reference is to be had to the accompanying drawings, forming part of this specification, in which I Figure 1 represents a side sectional elevation on line 1 1, Fig. 2, and Fig. 2 a plan, of the pulverizer. Fig. 3 represents a sectional elevation of a modification.

The same letters of reference denote like parts in all the figures.

The apparatus consists of a box a, in the center of which is fixed a post b, of cylindrical or other form, passing through a central aperture in a flexible diaphragm d, made of india-rubber or other elastic or flexible material, clamped between a seat in the upper edge of the box and a ring e screwing there- The inner edge of the diaphragm rests on a shoulder f upon the post b, which shoulder may either be coned for the purpose of slightly raising the said inner edge of the diaphragm cl, as shown in Fig. 1',or be made flat,

whereby it is pulverized. The diameter of the post I) may be reduced without affecting the action of the atomizer. In order to still further increase the fineness of the spray produced, air or gas may be introduced into the box along with the liquid either by the same or a separate pipe. The conical head It abovethe flange c is to facilitate the placing of the diaphragm d in position.

It will be understood that the form, dimensions, and details of the apparatus may be varied wiphout departing from the invention.

This liquid atomizer -or pulverizer may be used wherever it is desired to atomize a liq- .flexible diaphragm traversing said chamber,

and with a posttraversing the aperture in said diaphragm, substantially as herein shown and described. I

2. The herein-described liquid atomizer or pulverizer,- consisting in the combination of a chamber having an inlet, with an apertured flexible diaphragm, and with a post traversing the aperture in said diaphragm, said post having an abutment or projecting surface presented in the path of the film of liquid forced between the diaphragm and post, substantially as specified.

The foregoing specification of my liquid atomizer or pulverizer signed by me this 14th day of April, 1891.
